722a8ebe5b Store maximum transaction id into control file at clean shutdown.
This can serve to maria_chk to check that trids found in rows and keys
are not too big. Also used by Recovery when logs are lost.
Options --require-control-file, --datadir, --log-dir (yes, the dashes are
inconsistent but I imitated mysqld --datadir and --maria-log-dir) for
maria_chk.
Lock control file _before_ reading its content.


storage/maria/ha_maria.cc:
  new prototype
storage/maria/ma_check.c:
  A function to find the max trid in the system (consults transaction
  manager and control file), to check tables.
storage/maria/ma_checkpoint.c:
  new prototype
storage/maria/ma_control_file.c:
  Store max trid into control file, in a backward-compatible way
  (can still read old control files).
  Parameter to ma_control_file_open(), to not create the log if it's
  missing (maria_chk needs that).
  Lock control file _before_ reading its content.
  Fix for a segfault when reading an old control file (bzero() with a
  negative second argument)
storage/maria/ma_control_file.h:
  changes to the control file module's API
storage/maria/ma_init.c:
  When Maria shuts down cleanly, store max trid into control file.

storage/maria/ma_test2.c:
  new prototype
storage/maria/maria_chk.c:
  New option --require-control-file (abort if control file not found),

  --log-dir (path for logs).
  Try to open control file when maria_chk starts.

f094eff1d9 Injecting more "const" declarations into code which does not change
pointed data.
I ran gcc -Wcast-qual on storage/maria, this identified un-needed casts,
a couple of functions which said they had a const parameter though
they changed the pointed content! This is fixed here. Some suspicious
places receive a comment.
The original intention of running -Wcast-qual was to find what code
changes R-tree keys: I added const words, but hidden casts
like those of int2store (casts target to (uint16*)) removed const
checking; -Wcast-qual helped find those hidden casts.
Log handler does not change the content pointed by LEX_STRING::str it
receives, so we now use a struct which has a const inside, to emphasize
this and be able to pass "const uchar*" buffers to log handler
without fear of their content being changed by it.
One-line fix for a merge glitch (when merging from MyISAM).


include/m_string.h:
  As Maria's log handler uses LEX_STRING but never changes the content
  pointed by LEX_STRING::str, and assigns uchar* into this member most
  of the time, we introduce a new struct LEX_CUSTRING
  (C const U unsigned) for the log handler.
include/my_global.h:
  In macros which read pointed content: use const pointers so that
  gcc -Wcast-qual does not warn about casting a const pointer to non-const.
include/my_handler.h:
  In macros which read pointed content: use const pointers so that
  gcc -Wcast-qual does not warn about casting a const pointer to non-const.
  ha_find_null() does not change *a.
include/my_sys.h:
  insert_dynamic() does not change *element.
include/myisampack.h:
  In macros which read pointed content: use const pointers so that
  gcc -Wcast-qual does not warn about casting a const pointer to non-const.
mysys/array.c:
  insert_dynamic() does not change *element
mysys/my_handler.c:
  ha_find_null() does not change *a
storage/maria/ma_bitmap.c:
